BACKGROUND OF THE INVENTION
[0011] The present invention relates to a new and distinct cultivar
of Chrysanthemum plant, botanically known as Chrysanthemum x
morifolium, typically grown as a cut flower Chrysanthemum and
hereinafter referred to by the name `DLFLYCH7`.
[0012] The new Chrysanthemum plant is a product of a planned
breeding program conducted by the Inventor in Maasdijk, The
Netherlands. The objective of the breeding program is to create new
cut flower Chrysanthemum plants with unique and attractive
inflorescences.
[0013] The new Chrysanthemum plant originated from a
cross-pollination in February, 2017 of a proprietary selection of
Chrysanthemum x morifolium identified as code number db 33408, not
patented, as the female, or seed, parent with a proprietary
selection of Chrysanthemum x morifolium identified as code number
db 42809, not patented, as the male, or pollen, parent. The new
Chrysanthemum plant was discovered and selected as a single
flowering plant from within the progeny of the stated
cross-pollination in a controlled greenhouse environment in
Maasdijk, The Netherlands in October, 2017.
[0014] Asexual reproduction of the new Chrysanthemum plant by
vegetative terminal cuttings since October, 2017 in a controlled
greenhouse environment in Maasdijk, The Netherlands, has shown that
the unique features of this new Chrysanthemum plant are stable and
reproduced true to type in successive generations of asexual
reproduction.
SUMMARY OF THE INVENTION
[0015] Plants of the new Chrysanthemum have not been observed under
all possible combinations of environmental conditions and cultural
practices. The phenotype may vary somewhat with variations in
environmental conditions such as temperature, daylength and light
intensity, without, however, any variance in genotype.
[0016] The following traits have been repeatedly observed and are
determined to be the unique characteristics of `DLFLYCH7`. These
characteristics in combination distinguish `DLFLYCH7` as a new and
distinct Chrysanthemum plant: [0017] 1. Upright plant habit;
uniform growth habit. [0018] 2. Dark green-colored leaves. [0019]
3. Strong upright flowering stems. [0020] 4. Decorative-type
inflorescences with purplish red-colored ray florets. [0021] 5.
Resistant to Fusarium (Fusarium oxysporum) and Western Flower
Thrips. [0022] 6. Relatively tolerant to low production
temperatures. [0023] 7. Good postproduction longevity.
[0024] Plants of the new Chrysanthemum differ primarily from plants
of the female parent selection in ray floret color as ray florets
of plants of the new Chrysanthemum are purplish red in color
whereas ray florets of plants of the female parent selection are
purplish pink in color. In addition, ray florets of plants of the
new Chrysanthemum have more rounded apices than ray florets of
plants of the female parent selection.
[0025] Plants of the new Chrysanthemum differ primarily from plants
of the male parent selection in ray floret color as ray florets of
plants of the new Chrysanthemum are purplish red in color whereas
ray florets of plants of the male parent selection are red in
color. In addition, ray florets of plants of the new Chrysanthemum
are less carinate than ray florets of plants of the male parent
selection.
[0026] Plants of the new Chrysanthemum can be compared to plants of
Chrysanthemum X morifolium `Delibarca Red`, not patented. In
side-by-side comparisons, plants of the new Chrysanthemum differ
primarily from plants of `Delibarca Red` in ray floret color as ray
florets of plants of the new Chrysanthemum are purplish red in
color whereas ray florets of plants of `Delibarca Red` are deep red
in color. In addition, ray florets of plants of the new
Chrysanthemum have bluntly acute to obtuse apices whereas ray
florets of plants of `Delibarca Red` have mammillate apices.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
[0027] The accompanying photographs illustrate the overall
appearance of the new Chrysanthemum plant showing the colors as
true as it is reasonably possible to obtain in colored
reproductions of this type.
[0028] The photograph at the top of the sheet (FIG. 1) comprises a
side perspective view of a typical flowering stem of `DLFLYCH7`
grown as a disbud-type cut flower.
[0029] The photograph at the bottom of the sheet (FIG. 2) is a
close-up view of upper (left) and lower (right) surfaces of typical
inflorescences and typical leaves of `DLFLYCH7`.
DETAILED BOTANICAL DESCRIPTION
[0030] The aforementioned photographs and following observations
and measurements describe plants grown during the late winter in
ground beds in a glass-covered greenhouse in Maasdijk, The
Netherlands and under cultural practices typical of commercial cut
Chrysanthemum production. Plants were initially given long
day/short night treatments followed by short day/long night
treatments to induce flower initiation and development. During the
production of the plants, day temperatures ranged from 18.degree.
C. to 25.degree. C., night temperatures ranged from 20.degree. C.
to 22.degree. C. and light levels averaged 7 klux. Plants were
grown as single-stem disbud-type plants and were ten weeks old when
the photographs and the description were taken. In the following
description, color references are made to The Royal Horticultural
Society Colour Chart, 2015 Edition, except where general terms of
ordinary dictionary significance are used. [0031] Botanical
